Peptide dosage converter

Convert between micrograms, milligrams and international units. IU is not a unit of mass, so that conversion only holds for the IU/mg figure printed on the product.

Amount

mcg

IU per mg (from the product label, if stated)

IU/mg

Milligrams: 0.25 mg
International units: 0.75 IU

250 mcg ÷ 1,000 = 0.25 mg. IU is not a mass — the conversion holds only for the IU/mg figure printed on that specific product, and differs between products.

This tool does arithmetic only. It does not suggest an amount to use, and nothing on this page is a recommendation. Presets are vial and syringe sizes, which are packaging facts.
